If someone demonstrated to your boss that she could replace every piece of (fill-in-the-blank.. but think Sun) hardware with x86 machines that ran W2K3, maintain the same levels of performance and reliability, drop the Sun maintenance contract, and replace her expensive Solaris admins with cheap Windows admins, what do you think she might do?

I once worked at a place that had several dozen commodity Dell servers running NT, and several big pieces of Sun hardware. The NT servers were more reliable than the Sun machines, and they could support them in-house with salaried employees. Whenever the chance arose to replace a Sun machine with an x86 box, they took it without hesitation or regret.
